Launches on September 24, 2026

Experimental receipt country classification with Typesafe Jev and OCR, evaluated on multilingual text and image datasets from Hugging Face.

A portable Jev decision sidecar for coding agents: MCP, CLI, pi, source-bound context, durable budgets and measured outcomes.

Gate release risk from commits, tests, vulns, and incidents. Jev returns proceed, warn, hold, or review.

Performance and architectural analysis of the new "Jev" model by TypeSafe AI.

Recommend scale-down, keep, scale-up, or review from resource metrics with typed Jev decisions. Never changes infrastructure.

Suggest PR reviewers from CODEOWNERS, history, paths, labels, and teams. Jev decides; assignment stays explicit.

Reproducible experiment: can TypeSafe's Jev decision model prioritize SCA and SAST findings from context? Frozen benchmark, 50k scale run, frontier-model comparison, raw data and blog.

Gate SAST, SCA, IaC, secrets, and container findings with Jev. Returns PASS, WARN, BLOCK, or REVIEW without hiding findings.

Type words that fit a clue; Jev scores each and your car races ahead. Single-file, no build. Play free: jevtypesafeai.com/games/jev-semantic-racer

Sub-15ms context-window observability, deterministic decision gating, runtime self-healing, and continuous self-improving for AI agents using TypeSafe AI's Jev.

Route each task to the one tool an agent should call, with Jev — with confidence. Single-file, no build. Use free: jevtypesafeai.com/tools/jev-skill-router

A live support reply co-pilot built on TypeSafe AI's Jev model, evaluating tone, commitment risk, escalation, and predicted satisfaction in one parallel call while you type. Deployed on Cloudways Velocity.
